Application filed October `14, 1924. Serial No. 743,540.

This invention relates in general toimprovements 1n freight car roofs and more particularly to improvements in the class of car roofs usually designated as outside nietal roofs, which outside metal roof is movably or flexibly positioned on the car so as .to cover the wooden sheathing, or inside wooden roof of the car; and objects of the invent-ion are the provision of a metallic roof capable of movement in har- Inony with weaving motion of the car without the necessity Yof providing mullions spaced throughout the length of the roof to prevent the outside metal rooffrom shifting longitudinally; the provision of anchors for such car roofs which anchors are not exposed to the elements and which are arranged to hold the sheets from upward movement and from too great longitudinal movement; the provision of a roof which is simple to manufacture at a reasonable cost and which can be readily applied `without the necessity of specially skilled workmen and which when applied will be weathertight and not require frequent repair and replacement; the arrangement of the parts in such a roof so 'as to reduce to a minimum the number of points of Contact between the parts vto eliminate chafing especially at points exposed to the elements; and such other objects and advantages of the invention as may be found to obtain in the structure hereinafter set forth and claimed. I

In the accompanying drawings` forming a part of this specificationv andshowing,` for purposes of exemplification, a preferred form and manner in which the invention may be embodied and practiced, but without limiting the claimed invention specifically to such illustrative Vinstance or. instances'f Figure 1 is a. top plan view of a car roof embodying the invention, parts being broken away for better illustration. y

Fig. 8 is an end elevational view taken at the eaves end of a side seam cap. Fig. 9 is a top plan view ofthe. same, showing the arrangement of the anchor in dotted lines.

Fig. 10 is atop plan view of one of the anchors. Y

Fig. 11 is an end'elevational view of the car, the upper edge of which is flush with the upper surface of the adjacent side plate. 23 is the longitudinally extending side fascia, the upper edge of which is flush with the upper surface of the top edge of the side sheathing 22. The outer edge of the roof sheathing 21 extends over the top edge of the side sheathing and terminates at the inner surface of the side fascia.

The eaves edges of the roof sheathing 21 are gained `out at 24 to receive a longitudiY nally extending metallic flashing 25 whose inner edge terminate'sin 'an upwardly projecting open return bend hook 26 whose upper surface is below the plane of the top of the ungained roof sheathing and the flashing is flanged downwardly at 27 to enclose the outer edges 28 of the roof sheathing and then is bent outwardly at29 over the top surface ofthe side fascia vwhereit terminates in a depending flange 30 secured to the outer vside of the sidefascia.

v Roof sheets 31 are disposed von opposite sides of the ridge 32 of the roof, said roof sheets having inverted U-shaped ridge flangesA 32 lapped one over the othernand side flanges 33, said side flanges 33 consisting of an upwardly extending inwardly inclined portion 34 terminating in a downwardly ex tending portion 35 spaced from the portion 34 and the main body 36 of the roof sheet.

The' side flanges terminate at a. point 37 short of the eaves edge of the roof and the inifianged portion of' the eaves en( .side edge of the roof sheets are extended to forni en `tensions oi' ears 38, and at the ridge corners a portion of the ridge ilanging and side Hanging are cut away at 65 and the remaining portion of the ridUo flangiiig is folded bach on the portion oi' the side hanging as indicated at G6. roof sheets are flanged downwardly at and terminate in an outwardly pressed longitudinally extending rigidifying bead fil) that is arranged over and spaced from th outwardly extending portions 29 of the tions elllare bent downwardly to provide` two vertical side portions in contact with each other. `The portions t5 are bent outwardly at 4:6 to provide roof sheet hearino that vsupport the eaves edge of the roof sheets to limit rubbing of the flashing and ythe roof sheets, and these portions are pressed downwardly 4:7 to forin .seats i8 having apertures i9 Athrough whica ii or other fastening devices niay pass toV cure the anchors in place. il. portion of the top 43 and the vertical portionsl are cut away at 5l and a portion of the lower part of the contacting Aside vertical portions l5 are cutaway to provide a slot 52 into which the lapped ears 28 extend and are loosely` Confined as indicated at 53 so that the root' sheets niay have rooin to move accordingly as the cai' nieves and weaves.

Side seain caps intend frein ridge to eaves, said caps being of tubular forni and having curved sides 55 inwardly tui-'ned :it their lower endsaiidV terminating in upwardly extending flanges 56 spaced troni each otheil and troni the sides 5t) and when assembled onthe cai' the flanges 5o are arranged in the spaces provided betr n the portions 34- and of theside flan s i315 of the adjacent roof sheets. These side @sin `caps enclose the sides of adjacent roof -een at the eaves edge of the roof.` Vlhe eaves end of the side seain caps are closed by bending the` top down at 57 and the portion 5i' is sheets and the anchor thorebetn bent inwardly at 58 and the sides are then bent laterally at 59 over the portion l', as

indicated in Figs. -l and The ridge ends GO of the side seani capsare lapped one over the other and are capped by the corner end of theiidge cap 60'. i

A, running board saddle 6l ispositioned over the side ricain capsy said support! Y o() of the side seani caps, roof` sheathing The eaves edges of the ing the usual running boards 62. `To secure these parts in position a "bolt 63, passes through apertures in the saddle 6l, inverted U-sha-ped ridge cap 6 0, lappedridge ends 2l, and ridge `pole 64. A

To assemble theV roof on a cai', the anchors are secured over the flashing at proper distances, then the roof sheets are slidonto the roof towards the ridge that the side flanges of the roofsheets engage the holding dowiipoitions lllof the anchors as shown in Fig. 6, and the ridge endV flanges .are .lapped one over the other. Then the side seain caps `are slid toward the ridge onto the roof sheet side flanges and then the ridge caps `are arranged over the ridge flanges of the roof sheets and the lapped ridge ends of the side seain caps. The running board saddle is then positioned over the side` seam caps and the bolt 63 inserted as above described. At each end of the car .a innllion is provided which iscapped by` a tion but inay `be variously embodied within the scope of the claims hereinafter inade.
